But, the shortcoming of this scheme is: because this kind of lower temperature often just occurs occasionally in a year, so the use frequency of liquid ammonia pump is very low, like this not only causes the waste of system investment, but also affects the performance of liquid ammonia pump itself. is also unfavorable

Embodiment Construction
[0060] see figure 1 , which shows an ammonia gas supply system 100 using liquid ammonia as raw material according to the first embodiment of the present invention. The ammonia gas supply system 100 generally includes: a storage tank 10 (for example, made of steel) for storing liquid ammonia; an evaporator 20 for operably evaporating liquid ammonia flowing in from the storage tank 10 into ammonia gas; And a buffer tank 30 for receiving evaporated ammonia and outputting required ammonia. Wherein, as known to those skilled in the art, the storage tank 10 utilizes the unloading compressor to extract the ammonia on the top of the storage tank 10 through the storage tank pumping line 12 when feeding, and the ammonia tank car (not shown in the figure) Shown) the liquid ammonia in the storage tank is pressed into the storage tank 10 through the storage tank feed line 11; The buffer tank gas supply pipeline switching valve 32 and the buffer tank gas supply pipeline regulating valve 3...

The invention relates to an ammonia gas supply system taking liquid ammonia as a raw material, which comprises a storage tank for storing the liquid ammonia, an evaporator for forcibly evaporating the liquid ammonia flowing in the storage tank into ammonia gas and a buffer tank for receiving the evaporated ammonia gas and outputting the required ammonia gas. In addition, the ammonia gas supply system also comprises a reflux pipeline which is arranged between the storage tank and the buffer tank and is used for optionally refluxing partial ammonia gas which is forcibly evaporated in the evaporator to the storage tank. The ammonia gas supply system utilizes a mode of forcible evaporation and reflux of the liquid ammonia to ensure that the self pressure of ammonia in the storage tank can make the liquid ammonia normally flow into the evaporator for evaporation even at lower environmental temperature, thereby eliminating the requirement on a liquid ammonia pump, reducing the system investment and ensuring that the running of the system is more reliable.
Description
technical field [0001] The invention relates to an ammonia gas supply system, in particular to an ammonia gas supply system using liquid ammonia as a raw material. Background technique [0002] The ammonia gas supply system using liquid ammonia as the raw material is often used in flue gas treatment systems that use ammonia gas as the reactant, such as ammonia flue gas desulfurization and flue gas denitrification systems. The general flow of the ammonia gas process system with liquid ammonia as raw material is as follows: liquid ammonia is stored in the storage tank, the liquid ammonia flows into the evaporator to absorb heat and is forced to evaporate into ammonia gas, and the ammonia gas at the outlet of the evaporator flows into the ammonia gas buffer tank for the following The system provides the required ammonia. This common method generally uses an external evaporator to complete the evaporation of liquid ammonia. However, when the ambient temperature is high, liquid...
